Hop substitution list. Flavor wheel. Lets you save recipes. Gives you pre and post boil measurements. Also can edit/add new hops/grains to the database.
Ive never used the option but they have a full timer for your whole brewday. Alarms ring when mash/boil is done. Also records when yeast is pitched and alarms 2-3 weeks later to what you set it.

I own both Beersmith and iBrewmaster for iPhone. iBrewmaster is way better as it lets you modify/adjust your recipes as needed.

I manually have to type in my ingredients and mashing process, but it's super helpful and I usually hit my numbers dead on to what iBrewmaster predicts. I do know though that they're working on a revamp of that software, but it isn't clear whether that's a paid or free update. If paid, that will suck... but I'll probably buy it.

They're also working on a better version of Beersmith (a non-Lite version) which I think is supposed to be out in the spring.

I agree that there is a learning curve, but with a little time you'll be able to design your own recipes and compare them to style indicators, easily manage dates for racking and bottling, and use the timer clocks for both mashing and hop additions during the boil. iBrewmaster, HBT and Pandora are essential apps for brewday!

I used Brewpal for a few years but updates killed sme functionality and then one day it kept crashing. I got fed up and bought iBrewmaster. It is better than Brewpal, albeit a bit more complicated. I'm a fan, and recommend it. They seem to listen to the customers as well by adding features.
